Hercule Poirot finds himself in the middle of an elaborate onboard murder. Classy all-star version of the Agatha Christie warhorse. The business of the plot makes in-depth characterisation problematic, but everyone gets their moment to shine, with no resorting to the opening out of the recent Branagh version.
An Arctic scientific expedition is used as cover for different factions searching for old U-boat pens and Nazi gold. Great location work and impressive sets, plus a strong cast, enliven this otherwise-talky thriller adapted from an Alastair MacLean novel.
